Novagen sells BL21, a strain that works nicely for several recombinant 
proteins, I think it may also be available thru Stratagene.  Good Luck

I[m looking for E coli strains with as many protease genes inactivated 
as possible. The protein I[m trying to express (His-tag, Qiagen) is 
rapidly degraded in all the strains I have tried. I would prefer strains 
that are Kan-s and Amp-s. Grateful for all suggestions.
